books are on sale for $8

Peter has $25 dollar in his wallet

let the numbers of book be x

so,

if a book cost $8

x number of books cost $25

lets put it into mathematical statement

1 = $8

x = $25

lets cross multiply

1 X 25 = 8 X x

25 = 8x

8x = 25

divide both sides by 8

8x/8 = 25/8

x = 25/8

x = 3.125

x = 3 (approximately)

recall, we say x is the numer of books

so,

the number of books peter can by with is $25 in his wallet is 3atement
